APPLICATION DATA The TURBOSWITCH is especially designed to provide the lowest overall power losses in any "FREEWHEEL Mode" application (Fig.A) considering both the diode and the companion transistor, thus optimizing the overall performance in the end application. The way of calculating the power losses is given below:
TOTAL LOSSES due to the diode P = P1+ P2+ P3+ P4+ P5
Watts
CONDUCTION LOSSES in the diode
REVERSE LOSSES in the diode
SWITCHING LOSSES in the diode
SWITCHING LOSSES in the tansistor due to the diode
